You can easily share your Omniweb bookmarks with others across your network.
Omniweb stores bookmarks in a standard HTML file, which can be read by any browser on any OS. In Omniweb, choose Omniweb::Preferences::Bookmark on the menu and change the location of your bookmarksfile to file:///~/sites/bookmarks.html
Provided of course that you have switched on the Apache webserver, your bookmarks can now be accessed at http://yourmachine/~yourname/bookmarks.html. If you haven't yet built any HTML pages, you might even name the file index.html and it becomes the default file, so http://yourmachine/~yourname brings it up. You can still edit the file by simply maintaining your bookmarks in Omniweb, no HTML required.
I use this trick to access my bookmarks from Opera on NT4.
P.S. would love to login here, but can't, probably because I have switched off cookies. Oh well .Cubist
[Editor's note - yes, cookies are required for a login ID. Sorry!]
Another great reason to use OmniWeb -- OmniWeb's View Source is also an HTML editor!
The source pane is fully editable. Save will save over a local file and will make a new local file if it the page was serverd from a web server. Additionally, Store will store it back onto the server using WebDAV.
The kicker is that you can play around with remote files that are not your own VERY quickly.
Find any page on the web, View Source, make a few changes, and hit the Redisplay button. Voila! You will see your changes back in the browser in context with the rest of the original page. Pick apart layouts tricks at light speed...
OS X lets you specify any browser you'd like to use as your default (the browser that's used when you click on a URL) in the Internet system prefs panel. I prefer OmniWeb, and have told OS X so on several occasions. Unfortunately, for many people (myself included), this setting is lost between restarts.
A workaround was snipped from Resexcellence and sent to me, but I can't find the original on Resexcellence, so I can't provide a direct reference. However, if you'd like to make it at least a bit easier to get OmniWeb back as the default, read the rest of this article for the how-to.
Since it seems to be a little known tidbit, Mozilla actually has been carbonized and ported to OS X - the port is called "Fizzilla" and can be found here: http://www.mozilla.org/ports/fizzilla. So far, it's working pretty nicely - though its rendering is not as good nor as fast as that of Internet Explorer.
If you have a scroll wheel mouse, you can use OmniWeb to 'hover scroll' background windows. Try this experiment.
Open two OmniWeb windows that require vertical scrolling, and position them so that you can see a fair bit of the back one. Move the mouse over the back window, and use your scroll wheel without clicking in the window to activate it. It scrolls! Move the mouse over the front window, and you'll scroll that one instead -- no clicking required.
I imagine this is a feature, but I'd never noticed it before. Could prove useful at times.
This probably goes in the category of "How come you didn't know that already?!" but I think it's worthy of a mention. I've started using OmniWeb (as of fc3) as my (nearly) full-time browser, so I'm just starting to learn its subtleties. One thing that bugged me in earlier builds was the layout of the navigation bar.
This morning, by complete accident, I noticed you can move the objects on the bar by dragging them with the "command" key held down -- cool! In addition, as pointed out in the comments, control-click in the nav bar in an empty location, and you'll see a sheet of further customization options. Very impressive!
I now have a layout that I find much more usable. As a general comment, I really like the latest OW, even though it does some not so good things on this page (the "Favorite OS X Apps" box gets muddled pretty badly), and I can't yet use it with my home banking service. It's very fast and stable, and the page rendering is beautiful! They'll be getting a check from me, as I like the idea of supporting Microsoft competition!
